Key Takeaway
If your team is considering AI tools to speed up incident investigation, trial them on low-risk cases first and keep a person responsible for checking the results.
OpenAI has published an account of how its own engineers use Codex Ultrafast to investigate incidents in minutes rather than hours. The article points to faster security analysis as one of the main benefits of the tool.
According to the summary, the same tool is also used for code refactoring and for everyday engineering workflows. This suggests AI coding assistants are moving beyond writing code and into the operational work of security and incident response.
The summary does not give detailed figures, methods or limits of the approach, so businesses should treat the claims as a vendor's description of its own use rather than independent evidence.
